Specification of Letters Patent. Patented Mar, 16 11915,

Original application le October 2S, 1912. Serial No. 728,064. Divided and'this application led February 2'?, 1913. .Serial No. 751,082.

T0 aZZ whom it may concern Be it known that I, ONESIME E. MICHAUD, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have inventeda new. and useful Improvement in J ournal-Bearings, of which the' following is a specification.

The subject matter of the present invention is divided out of an application for Letters Patent of the United States, for'vehicle wheel filed by me on October 28, 1912, Serial Number 7 28,0621.

The present invention relates more particularly to anti-friction journal bearings` for vehicle wheels and the likeand it has for its principal objects to relieve the supporting anti-'friction elements of end thrust; to provide sim'ple means for taking the end thrust in both directions; and to attain certain advantages which will hereinafter more fully appear.

The invention consists in the parts and in the arrangements and combinations or parts hereinafter described in the claimsj;

In the laccompanying drawing which,

they occur,-Figure 1 is a longitudinal sec-r tion through a demountable wheel hub show ing an adaptation of the invention thereto; vFig. 2 is a similar view illustrating amodilication of the invention.

Referring now .more particularly tosFig. 1, the wheel hub comprises a permanent box 1 which is journaled on the axle arm 2. A demountable outer shell'or box 3 is slipped over said vpermanent box 1 and interlocked to rotate therewith, preferably by providing radial studs 4 on said permanent hub box which lit inrecesses provided at the inner The outer shell 3' is secured on the permanent hub box 1 by a :cap 5 which is screwed onto the outer end of said permanent hub box.

The axle arm 2 may be either of one diameter throughout or of two diameters as shown. Bearing sleeves 6, 7 are slipped on said axle arm and located respectively at 'the inner and outer end thereof.

These sleeves are provided with circumferential grooves in which cylindrical bearing rollers i5, 9, are respectively i'itted. The rollers are arranged in annular series and spaced apart by suitable cage rings 10.` Said cage rings also retain the rollers on the sleeves 6, 7,

ably placed on opposite sides of said col-l lar 12.

A filler sleeve or collar 16 is slipped on the axle arm between the two bearing sleeves 6, 7, said sleeve being of a length so` as to space said bearing sleeves apart just so thatthere is little or no play in the end thrust bearings provided by the balls 13. The outer end of the axle arm is screw threaded as at 17 to 'receive the securing nut v 18; and the relative lengths of said sleeves 5, 7, are such that when the nut is applied,

,said sleeves 6, 7, 'and said spacing sleeve 16 Y forms part or' this specification, and where are clamped between said nut 18 and the in like symbols refer to like parts wherever -v l'shoulder 19 provided at the inner end of the.

axle..arni. Hence, the sleeves 6, 7, and 16, are thus held from rotating with the hub of the wheel.

In the modification shown in Fig. 2, an ordinary.. non-clemountable hub box 20 is shown.r This hub box is provided with an internal collar l2a and the supporting and end thrust bearings are arranged substantially the same as in the structure shown in Fig. 1, but instead of providing the spacing sleeve 1G and clamping the bearing sleeves on the axle arm, a sleeve 16a is placed between thenut 18 and shoulder 21 provided by reducing the outer end portion of the axle arin. 1n this case, the nut 1S clamps the sleeve 16a against said shoulder 21, said sleeve being of a length just sufficient to allow the desired amount of play -in the end thrust bearings between said collar 121 and the bearing sleeves 6, 7.

yIn ca se the ysleeve 16 is used and -wear occurs in the end thrust bearings, said sleeve may be shortened or a shorter sleeve substituted, and ay shim or washer of a thickness corresponding to the portion that is removed from the sleeve inserted between the nut and .the adjacent end of the bearing ring 7. W hen the sleeve 16a is used as shown in orrron.

Fig'. Q, it is onlyl necessary to shorten -said sleeve to take up the wear in the end thrust bearings,

By the in set forth' the supporting bearing rollers 8,-9, are relieved entirely of end thrust and y 'the respective bearings are easily applied 1. y'.l`hecoinbination with an'axle member having an annular shoulder at its inner end,l

, the outer end of said axlemember being reduced to provide a'second annular shoulder,

said reduced end portion of the axle ineinber being screw-threaded, of a hub box having jouriialbearing portions near each end andan internaletlirust collar between saidI bearing portions, journal bearing sleeves slipped on said axle member and being slidable endivise in cooperative relation to the respective bearing portions of said hub box,

antifriction thrust bearings interposed between said bearing sleeves on the axle member andv said internal thrust collar on .the

hub box, one of said bearing sleeves abut.

ting against the annular shoulder-,at 'the inner end of said axle member andthe other bearing sleeve overhangingr .the reduced outer endportion of the axle member, a

arrangements of the bearings here-l Kcollai'c `sleeved on said reduced end portion of the axle member inside of the bearing sleeve and abutting against said second an nular shoulder, and a nut on the lscreW- 40 threaded portion of the axle member adapt; l ed. for holding the adjacent bearing slee.vel on the axle member, saidnut being also adapted to clamp said collar against the.l ad-v, jacent annular shoulder on the axle member,y whereby the Width of said collar controls-l the play between said end-thrust bearings@ '2.
